A day after announcing he would play basketball at Kansas, Cliff Alexander signed his letter of intent Saturday.

Alexander, the No. 4 overall recruit in the Class of 2014, made his decision Friday in a ceremony at Curie High School in Chicago in which he initially picked up an Illinois hat, then put it down and put on a KU hat.

KU assistant Jerrance Howard, who recruited the Chicago area as an assistant at Illinois from 2007-12, recruited Alexander.

“We are so excited about Cliff,” KU coach Bill Self said in a statement released by the school announcing the signing. “Since Jerrance Howard has been on board, he has done a great job in recruiting both Cliff and his family.

“Cliff comes here from a long line of great ones from Chicago and has as much potential as anybody in the class. At 6-foot-8, he can play on the block and he can play behind the arc. He can play in between, but the biggest thing he can do is rebound the ball. He’ll remind our fans of a Thomas Robinson going after the ball rebounding.”

Kansas has two members in its 2014 class. Small forward Kelly Oubre, rated as Rivals’ No. 12 overall recruit, signed with Kansas on Wednesday after verbally committing to KU over Kentucky in October following his visit to Late Night in The Phog.

“The combination of Cliff and Kelly Oubre gives us what we feel are two of the top players in our class and is a great momentum boost going forward this season knowing we’ll have some real good players waiting to get here next year,” Self said.

The addition of Oubre and Alexander fills Kansas’ two open scholarships. Senior forward Tarik Black is the Jayhawks’ only scholarship senior, while freshman Andrew Wiggins is a lock to leave early for the NBA Draft.

The Jayhawks, of course, also feature two other freshmen — Wayne Selden and Joel Embiid — who are potential first-round picks.
